Diesel Deficit Outlasts the War Shock

Diesel exports from Russia and the Middle East fell by 1.3 mb/d in September. Reuters put that loss at about 4.5% of this year's forecast global diesel and gas oil demand. That sounds small until you remember how little spare diesel the world holds.

The International Energy Agency's October Oil Market Report, published 14 October 2026, says the shortfall will outlast the shock that caused it. Oil balances stay in deficit through the end of the year, and constrained middle distillate supplies are likely to persist well into 2027. The emergency releases meant to cushion the blow have slowed. The IEA's governing board is now weighing whether to order more.

The shortfall

The IEA reports that combined net gasoil exports from the Middle East and Russia dropped to 820 kb/d in September, down more than 60% year on year. Other suppliers filled only part of the hole, leaving global diesel exports 700 kb/d lower than a year earlier.

Prices showed the strain. Wholesale diesel topped $200/bbl in Singapore in mid-September, and in Europe and the United States it reached all-time highs of around $220/bbl, the IEA says. Reuters reported that diesel refining margins, the fuel's premium over crude, hit record highs of almost $95 per barrel in September as lost refining capacity cut output. The National reports that US diesel pump prices topped $6 a gallon for the first time in September.

The stockpile behind those prices is thin. OECD gasoil inventories drew counter-seasonally to 565 mb in July, the lowest since November 2023, the IEA says. The National adds that US diesel stocks ended September at a 14-year seasonal low.

A slowing release

The IEA's remedy was a coordinated stock release agreed in March. Reuters reported that it ran at an average of 2.2 million bpd over March-June, then slowed to around 270,000 bpd in September. Reuters also reported that 331 million barrels had gone out by the end of that month. Europe still had 46 million barrels to release, the Americas 40 million and Asia-Oceania 10 million.

Pledges rose to 426 million barrels over time, and about 100 million barrels is still to come, Reuters reported. Governments hold publicly owned emergency stocks equivalent to around 1.1 billion barrels, including over 200 million barrels of diesel, the IEA said on 7 October. Members backed releasing diesel first.

Politics is now speeding things up. Reuters reported, in a story carried by Yahoo Finance, that the board will discuss the scale and timing of further releases after President Donald Trump told EU countries to draw down emergency inventories or face a potential US diesel export ban. He is trying to lower prices before the November 3 midterm elections.

Sparta Commodities analyst Abhishek Kumar told Reuters: "A 20- to 30-day release would represent a major intervention." He calculated that a 50 million-barrel draw over 30 days could broadly offset the estimated 1.6 million barrels per day of lost exports from Russia and the Middle East Gulf.

Europe's room to deliver is narrower. Kpler data show EU diesel and gasoil imports fell by 390,000 barrels per day between March and September. Reuters calculated that a 50 million-barrel diesel release spread over four months would provide roughly 400,000 bpd, broadly matching that decline. But EU rules require emergency stocks to cover at least 90 days of net imports or 61 days of consumption, whichever is greater, so any draw must be balanced against that floor.

Why a release will not end it

Easing Russian export restrictions will not rescue the market. The IEA says the move is unlikely to materially alter the global balance, because Russia's constraint is a lack of operational refinery capacity, not policy. Even a rapid refinery recovery into year-end leaves gasoil supply short of demand in the fourth quarter. On restocking, the agency's verdict: "unlikely before 2H27."

The IEA sees the gasoil and diesel market returning to surplus in the first quarter of 2027. That surplus, it says, will not offset the deficit built up during this year. Its warning is blunt: "oil markets may experience more turmoil in the months ahead before any eventual surplus emerges in 2027," the agency wrote, as quoted by Reuters.

Crude is sending mixed signals. Brent December futures held at $106.06/bbl at Wednesday's settlement, advancing 0.35% on the day, and WTI November futures at $95.09/bbl at Wednesday's settlement. Physical crude is dearer: the IEA says North Sea Dated traded around $134/bbl at the time of writing, after reaching $116.89/bbl in September. Energy equities have followed. XLE stood at $67.20 at Tuesday's close.

Diesel margins have eased. Reuters put the European benchmark margin around $85 per barrel, down from an all-time high of close to $95 in late September. The IEA's own measure shows cracks for European refiners falling from $100/bbl to close to $60/bbl by early October as freight rates soared and crude got costlier to deliver. Traders Union, relaying the Financial Times, says analysts expect some European refineries could soon assess cutting runs if profitability weakens further. US refiners can burn domestic crude and avoid tanker-shortage freight costs, leaving them positioned for a sharp rise in profits, the same report says.

Cutting runs in Europe would deepen the diesel shortage.

The demand escape valve

If supply will not recover, demand has to give. The National reports that the 2027 oil demand forecast was cut by 630,000 bpd, with consumption still 620,000 bpd below 2025 levels. The agency also warned that further consumption cuts may be needed if Middle East refined-product exports do not recover.

The US EIA is more hopeful on price. Its October outlook has Brent averaging $105/b in the fourth quarter, falling to $87/b by the second quarter of 2027 and $74/b in the fourth as depleted inventories rebuild. That path assumes the barrels return. The IEA's diesel data say the refineries to turn them into fuel will not be ready.
